Is it possible for something to be wrong with the boot blocks on the second drive, even though I can use the drive to store data? I have been using the second drive for a while and have not had any trouble. 2. What do the boot blocks do? 3. Where should I look to verify that the boot blocks are working correctly? Is it enough that I was able to label the drive and newfs the partitions? One more point. I used the same boot blocks for both ide drives (the ones on the install floppies), does this rule out the chance that something is wrong with the boot blocks? I also suspect that my second drive may do geometry translation (its a connor cp3544) and I have not turned it off (just faxed connor to ask how) could this have something to do with my problems? BTW, someone asked if I had put the wd1b in /etc/fstab. Yes I have, and swapon is also run. The other option I have is to start looking into why dmesg or swapinfo fails. It will probably involve looking into why something in the kernel is failing...I've never used kdb, can someone give me some pointers on how to debug the kernel. -Ram -- -------------- Ram Bhamidipaty use this ->ram@epidat.epi.wisc.edu Department of Preventive Medicine or this->ram%epidat.decnet@macc.wisc.edu University of Wisconsin, Madison Ignore the header.
